Transportation agencies at the state, provincial, and local levels receive many requests to display non-urgent messages on Dynamic Message Signs (DMS) regarding advertising, safety messages, and special events, for example. Agencies must decide how to respond to these requests. In addition to state, provincial, and local level policies and preferences about the use of DMS, federal design standards such as the Federal Highway Administration (FHWA) Manual of Uniform Traffic Control Devices (MUTCD) must also be considered when deciding which requests to approve.

This project conducted an online search to gather state, provincial, local, and federal policies and guidelines for DMS messaging. The search also included documenting related DMS studies or efforts. Transportation agencies were also contacted to provide additional details on information gathered through the online search. In addition, ENTERPRISE members provided input throughout the duration of the project to enhance the search for DMS messaging related documents and guidelines. A survey was distributed to state, local, and provincial transportation agencies to gather additional details on the DMS message requests received by transportation agencies as well as the policy or process for handling DMS message requests. The project also researched the potential for public-private partnerships for DMS deployment and operations and documented a few potential future scenarios for connected and automated vehicle implications on DMS.
